Optical Sensor of Thermal Gas Flow Based on Fiber Bragg Grating

Optical Sensor of Thermal Gas Flow Based on Fiber Bragg Grating

This paper aims at solving the problem of explosion proof in measurement of thermal gas flow using electronic sensor by presenting a new type of flow sensor by optical fiber heating. A measuring unit based on fiber Bragg grating (FBG) for fluid temperature and a unit for heat dissipation are designe...
